To all whom it may concern: 4

Be it known that I Tnoams C. J OIINSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State'of Connecticut, have invented a new and useful Improvement in Repeating when taken in connection with the accompanying drawings and the numerals of reference marked thereon, to be a 'full, clear, andexa'ct description of the same, and which said drawingsconstitute part of this specificatioinand represent, in

Figure 1 a broken'view .in vertical longitudinal section of a gun constructed in accordance with my invention and shown as closed and locked, and with the hammer in its'fired position, my new combined part being, however, shown by full lines in the position it has just before firing the gun, and in broken lines in the position it has just after firing the gun..- Fig. 2 a corresponding view of the gun showing the breech-closure at the point in its rearward excursion where cocked position in which its cock-notch is part being shown in the temporary clearance position which takes during the rearward movement of the closure for the purpose of pass by the beak of the locking-hook of the said part. Fig. 3 a corresponding view at that point during its forward excursion at which it is disengaged from the hammer and closes to control the same which takes clearance cut in the action-bar has acted upon the for ard end of the blockmg-arm of the combined part to depress the same over the locking-lug of the hammer which is thus prevented from falling even though the trigger should be pulled at this time.

My invention relates to an improvement in that class of repeating firearms, the mechanism of which is operated by a sliding handle located forward of the gun-frame or receiver and connected with the mechanism of the gun by means of an action-bar, the objOt'l of my invention being to guard against the premature opening or firing of the gun, by mechanism of simple, positive and reliable character.

\Vith these ends in view my invention consists in a repeating gun having certain details of construction and combinations of parts as will be hereinafter described and pointed out in. the claims. I i

In carrying out my invention as herein shown, I form a bevel 2 upon the extreme rear end of the action-bar 3 which is connected at its forward end in any approved manner with the rear end of the sliding operating-handle or forearm 4 which is mounted to slide upon tho-tubular magazine 5 located beneath the gun-barrel 0.

The said bevel? at the rear endof the bar 3 coacts with a corresponding bevel 7 located upon the upturnedforward end of the blocking-arm 8 011a combined part which also comprises a hannner-locking hook 9 and a manuallyoperated arm 10, and is formed at the base of the book 9 with a-pivot-hole 11 receiving apivot 12 passing through the upper portion of the guard 13 which is sccured to the lower portion of the gun-frame or receiver 14 which is formed with a solid top and in its right-hand side wall with an ejection-opening which is not shown, and in its bottom with a feeding-opening 15. The said combined part functions as an actionbar lock and provides for opening the,gun manually without firing it. For con venience I shall speak of this part as the.- combined part, since it acts as one piece and is prefer- Fig. 10 a swings in a vertical plane 011 the pivot 12, is formed with a hub 16 extending from left to right and carrying a two-legged spring havmg a lower leg 17 and an upper leg 18 extending forward and respectively coacting with the lower point 19 and the uppcr poi'nt 2001 a lug 21 located upon the inner or left hand face of the hammer 22 which is mounted upon a pivot 23 and formed with'a cockn'otch 24 rcwiving a scar 25 made integral ical spring. This s 7 end in will be expla part, I employ a spring 37 consisting of a of the combined its pivot 12 and its forward even thou h the t r ulled so as to dise gage th e zir closure 30 should be 25 f with a trigger 26 hung upon a pivot 27 inthe guard 13. A small helical spring 28 entering. the lower face of the sear 25 provides for entering the nose thereof into the cocknotch 24 of the hammer 22.

or coaction with the hammer-lockinghook 9 of the said combined part, the hammer is formed upon its inner or left hand face with a locking-lug 29 which coacts with the beak. of the said hook to prevent the hammer from followingso to speak, the breech-closure 30 in the forward or closing movement thereof and from bein fired in case the user of the arm should pull the trigger at this time after. the closure in its forward movement has left the hammer in its cocked osition. The said breech-closure 30 is of t e compound be held by the said arm 8 and therefore independent of the trigger and sear, in its cocked position while the breech-closure 30 is being moved into its fully closed and look I ositionby the ,action-bar 3. After the reech-closure has been movedinto its closed tion, the action-bar is moved still farther forward so as to clear its rear end from the front end of the blocking-arm 8 and permit part on its pivot 12 and so lift the arm 8 in position to lock the rearward movement of the action-bar which is set back so to speak, to keep its bevel 2 engaged with the bevel 7 of the arm 8 bythe spring 37 which was placed under tension for this verypur so at the end of the forward ex curs1on of tlie said bar. Now when the spring 18 rocked the combined scribed, the hammer-locking book 9 was swung back clear of the lug 29 of the hamhammer 22 is provided, as usual,

At its rear end the manual arm 10 of the combined part is formed with a finger-piece 35 which projects downward through a cut served, the hammer against being so released until after the gun was fully closed and locked.

' lu 43 which travels in a cam-pat 44 in the For maintaining the engagement, under normal conditions, of the bevel 2 of the action-bar and the bevel 7 of the combined this cam-path being suitably conformed for raising and lowering the closure at its rear d as required.- It will be observed by reffla't broken ring forming one coil of a helrence to Fig. 3, that the enlarged rear end ring encircles the tubular ma azine-5 an is interposed between a fixed co lar'38 on the same, and a collar 39 located within the rear end' of the sliding handle 4 and exerts a constant effort to ress the bevel 2 of the rod 3 against the bevel'7 part, being enough more powerful than the upper leg 18 of the two-' legged spring before referred to, to overcome the t ndency of the said leg 18 to move the blocking-arm 8 ofthe combined art downward out of the path of the actionar 3. Y

For the purpose of momentarily permits ting the hammer-locking hook 9 to incline rearward as the hammer 22 is swung rearward by the breech-closure 30 during the rearward excursion thereof, the lower inner face ofthe action-bar 3 is formed with a long clearance cut 40 terminating at. its rear a depressin cam 41 which in the forward movement 0 the action-bar 3 engages with the beveled rear edge 42 of the upturned end of the blocking-arm 8 ofthe combined part, whereby'lthe same is rocked on hook 9 swung forward 1 of the cam-path 44 is longer in the dire of the axis of the closure than the lug 43 which permits the action-bar to travel a short distance at the veryvbeginning of its forward and rearward begins to take effect hpon the closure. these two excess or in ependent movements 0!." the action-bar only theforward movement is utilized, that being used as a timing movement to change the the action-bar 3 part for causing the depressing cam 41 at said bar to gain, so to speak, upon the bevel 42 upon the rear edge ward end of the bloekin -arni 8 of the combined part so that in c osing the unjust before the rear end ofthe breech-o is disengaged from the hammer 22, the dcpressing=cam 41 will catch up with the bevel 42 and rock the combined art on its pivot 12 a ainst the tension of t e leg 18 of the twoegged spring, whereby the hookv9 of the combined part will swing over the lug 29 of the hammer 22 and ho d the hammer over the ln 29-of the hammer-22 which isinits cocked position by the hook 9 irrethereafter heldfagainst following the breechspeetiveofjthe scar and trigger.

excursion'before it of the upturned forosurc 30 v operating handle which experience has shown the'user tends almost unconsciously to pull back upon rather than to push-forward.- When the gun is recoil causes a momentary separation between the rear end of the action-bar 3 and the forward end of the arm 8which latter is then thrown down out of the path of the action-bar by the tension of the leg 17 of the two-legged spring, this leg of the spring having been placed under tension by the lower corner 19 of the lug 21 upon the hammer in the following movement thereof. Even if the user of the gun is pulling rearward upon the handle at the time the gun is fired, the gun will be mlocked as the force of his rearward draft upon the handle will be inferior inv power to the shock of recoil; but no matter how hard he pulls rearward upon the handle, the gun will always remain locked until the cartridge explodes, whereby all cases of delayed ignition or f hang-fires? are taken care of; I

During the rearward movement of the action-bar in opening the gun, its clearance cut 40 is brought into registration with the upturned end of the blocking-arm 8 of the combined part, which is thus allowed to .swing in a vertical plane on its pivot 12 so as to bring the hook of the hammer-locking arm 9 into position for clearing the lug 29 of the hammer 22, so that when the gun is again closed the said hook will be in position to be swung forward over the said lug and thus hold the hammer in its cocked position irrespective of the trigger, from the time the control of the hammer by the breech-closure 3Q is removed, by the forward movement thereof. Just before the gun is fully closed,

the spring 37 is placed under sufiicient pressure to set the action-bar 3 back upon the arm 8 of the combined part so as to lockthe gun in its closed position against being prematurely opened by an unconscious rearward draft upon the handle it the time of firing. In case it is desired to open the gun without firing it, it is only necessary for the user to push forward on the fin er-piece 35 at the rear end of the manual? operated arm 10 of the combined part, the blockingarm 8 of which will then be moved down so as to clear the rear 'end of the action-bar The other features of the operation of the mechanism were so fully set forth'in connection with the description ofthe mech anism that it is thought unnecessary to rehearse them again.
